| Keep your friends close, cortisol levels low for life Posted: 30 Jun 2021 02:36 PM PDT An interdisciplinary team has determined that older adult women converse more effectively with strangers than their younger counterparts; additionally, communicating with female friends decreases stress hormone levels for women across the lifespan. |
| Human stem cells enable model to test drug impact on brain's blood barrier Posted: 30 Jun 2021 09:54 AM PDT Using an experimental model to simulate the blood-brain barrier, scientists reported in unprecedented detail how antioxidants protect the brain from inflammation caused by such neurodegenerative diseases as Alzheimer's and Parkinson's. |
| Researchers look to human 'social sensors' to better predict elections and other trends Posted: 30 Jun 2021 08:54 AM PDT Researchers can gather highly accurate information about social trends and groups by asking about a person's social circle rather than interrogating their own individual beliefs. |
| Employed individuals more likely to contract the flu, study shows Posted: 30 Jun 2021 08:54 AM PDT Researchers found that employed individuals, on average, are 35.3% more likely to be infected with the flu virus. |
| Eating disorder behaviors alter reward response in brain Posted: 30 Jun 2021 08:53 AM PDT A new study found that eating disorder behaviors alter the brain's reward response process and food intake control circuitry, which can reinforce the behaviors. |
| Cross-generational consequences of lead poisoning Posted: 30 Jun 2021 08:53 AM PDT Scientists have shown that environmental lead poisoning in children affects not only their own health and wellbeing, but the vitality and mental health of their mothers, as well. |
| Thinking in 3D improves mathematical skills Posted: 30 Jun 2021 08:53 AM PDT Spatial reasoning ability in small children reflects how well they will perform in mathematics later. Researchers recently came to this conclusion, making the case for better cultivation of spatial reasoning. |
| Discovery of the role of a key gene in the development of ALS Posted: 30 Jun 2021 06:13 AM PDT Amyotrophic lateral sclerosis, or ALS, attacks nerve cells known as motor neurons in the brain and spinal cord, gradually leading to paralysis. The loss of function of an important gene, C9orf72, may affect communication between motor neurons and muscles in people with this disease. |
| Mouse brain imaged from the microscopic to the macroscopic level Posted: 28 Jun 2021 02:05 PM PDT Researchers have leveraged existing advanced X-ray microscopy techniques to bridge the gap between MRI (magnetic resonance imaging) and electron microscopy imaging, providing a viable pipeline for multiscale whole brain imaging within the same brain. |
